REAGH COUPLlNG FOR VEHICLES.

SPECIFICATION forming part of Letters Patent No. 380,541, dated April 3,1888.

Application filed November 26, 1887. Serial No. 256,209. (No model.)

To whom it may concern.-

Be it known that l, STEPHEN M. WIER,.of New Haven, in the county of NewHaven and State of Connecticut, have invented a new and ImprovedFit'th-WVheel and Reach-Coupling, of which the following is aspecification, reference being had to the annexed drawings, forming apart thereof, in which-- Figure 1 is a plan view of my improvedreaclrcoupling. Fig. 2 is an inverted plan view. Fig. 3 is a sideelevation, and Fig. 4 is a section taken on line x w in Fig. 1.

Similar letters of reference indicate corresponding parts in all theviews.

The object of my invention is to provide a device for connecting thereach to the front axle of a vehicle, which will be provided with largeadj nstable wcaring'surfacesand in which the king'bolt is not subjectedto wear.

My invention consists in the combination, with the axle and reach of avehicle, of conical bearings secured to the axle, and conical socketsattached to the reach for receiving the bearings oi the axle, all ashereinafter more fully described.

To the upper side of the axle A, at the center thereof, is fitted acircular iron, 13, having a conical periphery, O, and an annular recess,a, for receiving the heads of the bolts 1), by which the iron is securedto the axle. The iron is also provided with clips 0, which embraceopposite sides of the upper part of the axle. To the under side of theaxle A is fitted the oblong iron D, having clips (I for embracingopposite sides of the lower parts of the axle, and provided with aconical projection, E. The irons B D and the axle A are centrallyapertured to receive thebolt F, by which the several parts of thecoupling are fastened The iron D is apertured to receive the bolts b, bywhich the said iron and the iron 13 are secured to the axle A.

To the conical periphery O of the iron B is fitted a conical socket, G,provided with a. central boss, 71, which projects into the central partof the iron 13 and has a square aperture, 6, for receiving the bolt F.An arm, H, formed integrally with the socket G, extends over the the armJ. The bolt Z extends through the arm H, the reach K, and the arm J,clamping the parts firmly together.

It will be observed that with my improved coupling the wear is removedfrom the kingbolt F, and is transferred to the conical periphery O ofthe iron 13 and the conical projection E of the iron D.

The conical form of the wearing-surfaces permits of adjusting thecoupling so as to take up wear and avoid rattling.

Having thus fully described my invention, 1 claim as new and desire tosecure by Letters Patent- 1. In a fifth-wheel and reach-coupling forvehicles, the combination,with the axle A and reach K, of the iron B,provided with the conical periphery G, the iron D, provided with theconical projection E, the socket G, provided with the arm H, and thesocket 1, provided with the arm J,substantiallyasspecified.

2. As an improved article of manufacture, a fifth-wheel andreach-coupling formed of the iron 13, provided with the conicalperiphery G and with clips 0, the socket (3-, fitted to the iron B andprovided with the arm H, the oblong iron D, having the conicalprojection E and provided with the clips 6., the arm J, having a socket,I, and the bolt F, adapted to hold the iron B, socket G, and the iron Dand socket I in the position of use, substantially as specified.

STEPHEN M. TIER.
